DDOS is vandalism, simply. We'd cover it if a mob was throwing rocks at Microsoft, RedHat og IBMs head quarters, would we not? This is just as much vandalism, and there *is* no justification for vandalism.
This is actually why I am no fan of groups like Anonymous, and do not cheer when they for example hit ISIS targets. There's bound to be a lot of collateral damage, and a lot of innocent people will be targeted.
As for Linode? God knows what they or some of their customers have done. But this time - like a lot of other innocent people - it actually hit *me* too. I got tired of running a physical machine at home just so I could run all my services, so I got myself a server at Linode. It has a lot better WAF, too.
So am I satisfied with Linode? You bet. This is not their fault. I am sure they are bound to learn from it, to quicker stop this in the future. But it is not easy, to stop mobs. Because DDOS groups are just that: Mobs! No matter how much you sympatize with a cause, a mob is never justified.
